Show a spinner on running operations

[cybercoder-naj]

When I am trying to connect with Bluetooth devices, I hit the <space> but I wasn't sure if that did anything. Some progress indication would be great to know that pressing <space> actually did something

Good point 💯
I will look at it

hi @pythops do you mind if i take this?
I'm thinking to change is_connected into 3 states: [DISCONNECTED, CONNECTING, CONNECTED]. But if it complicates other logics that depend on this state, i'd be happy to implement a spinner as originally proposed.

I think we need some refactoring first before implementing it and it would make it much easier after.
